🧪 GitHub PR Agent — Native GitHub Automation

The GitHub PR Agent runs automatically in GitHub Actions when a pull request is opened or updated. It detects changed code, analyzes coverage, generates targeted unit tests, and commits them back to the PR branch — all with zero manual effort.

Supported languages: JavaScript, TypeScript, and Python.

📌 When to Use​

Use the GitHub PR Agent when:

  • You're using GitHub Actions
  • You want fully automated test generation per pull request
  • Your team prefers a zero-config, GitHub-native workflow
  • You want to block merges without new tests

⚙️ How It Works​

  1. Triggered by PR open, update, or ready-for-review events
  2. Detects changed files in the PR diff
  3. Runs your existing test suite (Jest) to measure coverage
  4. Identifies under-tested functions
  5. Generates AI-powered Jest tests for those functions
  6. Commits valid tests (only if they pass and compile)
  7. Posts a PR comment summarizing coverage and results

🔐 Requirements​

  • ✅ Your repo must use GitHub Actions
  • ✅ Your project must use TypeScript or JavaScript
  • ✅ You must have an existing Jest test setup
  • ✅ Node.js 20+ must be available in your CI
  • ✅ A valid API_KEY must be configured
